A process for improving phosphatation clarification of sugars can include adding to a sugar liquor a composition having at least one particulate sulfur reagent and at least one or more other particulate solids selected from, a particulate phosphorous reagent, a particulate carbonaceous reagent, a particulate aluminum reagent, a particulate filter aid, and a particulate ammonium reagent. The composition can be added to the phosphatation chemical reaction tank or prior to the phosphatation chemical reaction tank. Phosphatation chemicals, for example polymer decolorant, phosphoric acid, lime and a flocculent, can be added into the process at least five minutes after adding the composition. In using the process, the amount of phosphatation chemicals added is less than the amount of phosphatation chemicals required in the absence of addition of the composition or the purity of the sugar is improved as measured by one or more of color, turbidity and ash.
A process of phosphatation processing of sugar liquors, comprising adding to a sugar liquor a composition comprising at least one particulate sulfur reagent containing at least one sulfur atom and at least three oxygen atoms, and at least one particulate phosphorous reagent containing at least one phosphorous atom and at least three oxygen atoms in the chemical formula, and optionally further comprising at least one or more other particulate solids selected from the group consisting of a silica reagent, a particulate carbonaceous reagent, a particulate aluminum reagent containing at least one aluminum atom and at least three oxygen atoms in the chemical formula, a particulate filter aid, and a particulate ammonium reagent having at least one ammonium group (NH4) in the chemical formula, wherein the composition is added to a phosphatation chemical reaction tank or prior to a phosphatation chemical reaction tank to perform the phosphatation processing.
A process of phosphatation processing of sugar liquors, comprising adding to a sugar liquor a composition comprising at least one particulate sulfur reagent containing at least one sulfur atom and at least three oxygen atoms, and at least one particulate phosphorous reagent containing at least one phosphorous atom and at least three oxygen atoms in the chemical formula, wherein the composition is added to a phosphatation chemical reaction tank or prior to a phosphatation chemical reaction tank to perform the phosphatation processing.
A composition for use in sugar refining phosphatation clarification, comprising from about 10% to about 90% of at least one particulate sulfur reagent containing at least one sulfur atom and at least three oxygen atoms, and from about 5% to about 90% of at least one particulate phosphorous reagent containing at least one phosphorous atom and at least three oxygen atoms in the chemical formula, and optionally further comprising at least one or more other particulate solids selected from the group consisting of a silica reagent, a particulate carbonaceous reagent, a particulate aluminum reagent containing at least one aluminum atom and at least three oxygen atoms in the chemical formula, a particulate filter aid selected from diatomaceous earth or perlite, and a particulate ammonium reagent having at least one ammonium group (NH4) in the chemical formula.
